Wi-Fi, or Bluetooth? It's a question that most audiophiles have answered resoundingly when it comes to wireless sound: Wi-Fi, of course. Uncompromised fidelity (from the original audio source), more stable connection, fewer interruptions, and did I mention fidelity? In the last year or two, though, we've basically seen Wi-Fi speakers pushed into a corner of the market, as a niche product, while ever more ubiquitous Bluetooth speaker systems have taken the lead.
